Can't update Git digests with jsonata

How are you running Renovate?

I have a YAML file with a list of dependencies that are downloaded from Git during a deploy process. The YAML file includes the Git repo URL, the branch name, and the commit hash. I want to keep the commit hashes up to date.

I'm using the JSONata custom manager and the Git refs datasource. The Git refs datasource documentation say to set currentValue to the branch name.

In the Renovate dashboard, I can see that Renovate detects the dependencies, but it has an error when trying to make a PR. I think it's only trying to replace the currentValue (which is the branch name, see the Git Refs Datasource docs) even though this is a digest update so it should be trying to replace the currentDigest.

It is a known limitation. I will create an issue to track it.

Linking to the original report: #36461 I tried to fix it but was unable to since I am not familiar with JS/TS

[RahulGautamSingh]

Can you try the fix I mentioned here and see if it works for your case.

[jalil-salame]

Haven't tried, but will give it a shot!
